DAGENI-IAR'I. 70of grid bars mounted in said casing adapted to cooperate with thebeater, said grid bars being divided into two sections with an openingtherebetween, a strip secured transverse- I 1y of the machine in theside walls of the said 7 opening, and a plurality of spaced grid barsmounted at right angles to the grid bars in said strip and being adaptedto admit air therethrough. 2. In a cotton picking machine having a gobeater casing and a beater mounted therein v with a plurality of gridbars adapted to cooperate with the beater, said grid bars being dividedinto two sections with a passageway v therebetween through which air isadmitted 85 into: the beater casing, and a plurality of spaced grid barsmounted at approximately right angles to the grid bars in said openingthrough which air is adapted to be drawn 05 into the beater casing. 7 so3. In av cotton picker, a casing, a heater mounted in said casing, twosections of spaced bars adapted to cooperate with the beater, apassageway disposed transversely of the machine, and being positioned between opposite sets of 'bars,'a plurality of spaced bars mounted atright angle to the grid bars of the machine and being spaced apart fromeach other whereby air is admitted into the beater casing from a pointother than that of the point where the cotton is admitted. 7
